Notes on codebase quality.
Practical writing on testing, architecture, dependencies and the long game of keeping a codebase shippable, from the team building the tools to measure it.
Per-PR vs Nightly Scans: When to Run Each CI Check
Some CI checks belong on every pull request, others belong on a nightly schedule. A practical guide to deciding scan cadence without slowing merges.
Code Maintenance Best Practices for 2026
Code maintenance keeps a codebase shippable for years, not just months. Eleven practical habits that separate a healthy repo from a fragile one.
What Is Deterministic Code Analysis?
Deterministic code analysis runs the same input twice and gets the same result. Learn what makes analysis deterministic and why it matters for gating.
How to Fix Circular Dependencies in JavaScript
How to fix circular dependencies in JavaScript and TypeScript: detect with madge, break cycles with type-only imports, shared contracts and DI.
How Automated Codebase Health Scoring Works
How automated codebase health scoring works: the signals, pipeline and feedback loops that turn a repository into a trusted, trendable quality number.
Codebase Health Monitoring: A Practical Guide
Codebase health monitoring tracks quality signals continuously so regressions surface early. Learn the signals, cadence, and alerts that matter.
Slow Drift in AI-Assisted Codebases
AI-assisted codebases do not break, they drift. Nothing looks urgent until it is. Why measuring change over time is the new quality problem.
Why Code Quality Matters More in the Age of AI
AI tools generate code faster than ever. Without quality measurement, speed creates risk. Learn why automated quality checks matter more now.
7 Code Quality Metrics Every Engineering Team Should Track
From test coverage to cyclomatic complexity, these seven metrics give engineering teams real visibility into codebase health.
How AI Coding Assistants Affect Your Codebase Health
AI assistants accelerate development, but what happens to architecture, consistency, and testing? Explore the benefits, risks, and fixes.
What Is a Codebase Health Score?
A codebase health score distils complex quality data into a single number. Learn how scores are composed, why they help, and their limits.
PR Quality Gates: A Complete Guide
Learn how to set up PR quality gates that catch real problems without blocking your team. Covers thresholds, domains, and common pitfalls.
The Hidden Cost of Skipping Code Reviews
Skipping code reviews saves time today but creates costly problems tomorrow. Learn how bugs, knowledge silos and security gaps compound over time.
Understanding Circular Dependencies and How to Fix Them
Circular dependencies cause subtle build failures, testing pain and tight coupling. Learn how to detect them and practical strategies for breaking the cycle.
Why Your Test Coverage Number Is Misleading
High test coverage does not guarantee good tests. Learn why coverage metrics can be misleading and how to use them as one signal among many.
Static Analysis vs AI Code Review
Static analysis and AI code review each have strengths. Learn how deterministic tools and AI complement each other for more effective code quality.
A Practical Guide to Managing Technical Debt
Technical debt is inevitable but manageable. Learn how to identify, prioritise and pay down debt without stopping feature work.
How to Improve Your Codebase Architecture
Practical steps for improving codebase architecture. Cover module boundaries, coupling, layered patterns and measuring progress.
Security Patterns Every Developer Should Know
Common security anti-patterns in web codebases and how to fix them, from committed secrets to SQL injection and CORS misconfiguration.
Why Documentation Is a Code Quality Signal
Documentation reflects how well a team understands its codebase. Good docs reduce onboarding friction and operational risk.
Keeping Your Dependency Supply Chain Healthy
How to manage dependency sprawl, lockfile hygiene, transitive vulnerabilities and licence compliance in modern codebases.
Performance Anti-patterns in Modern JavaScript
Common JavaScript performance mistakes: sequential awaits, N+1 patterns, heavy imports and large bundles. How to detect and fix them.
CI/CD Quality Checks That Actually Work
Most CI quality checks get ignored or bypassed. Learn how to design checks that teams respect with fast feedback and clear thresholds.
Accessibility in Code: Beyond the Frontend
Accessibility issues hide in code, not just designs. Learn how to detect common patterns like missing alt text and removed focus styles early.
How to Measure Codebase Maintainability
Maintainability is hard to quantify. Learn the concrete signals that reveal whether a codebase is easy or hard to work with over time.
What Makes a Good Quality Gate?
Quality gates must balance strictness with developer experience. Learn how to set thresholds, get buy-in, and improve standards over time.
